Since a few days, everytime I do something "invalid" in a gtk application, like pressing esc, when there is nothing to "escape from", or pressing backspace in an empty input field, I get a weird noise (it sounds a bit like a waterdrop).
I already tried setting this in my ~/.gtkrc-2.0:
gtk-enable-event-sounds=0
gtk-enable-input-feedback-sounds=0
but that didn't change the behaviour.
In case it's relevant, I'm on NixOS unstable
